I was just looking at the new lexical_cast implementation and unless I 
messed up with updating my tree to RC_1_30_0 the documentation needs to 
be fixed as well.

AFAICS the documentation nowhere mentions the change in semantics for 
string handling. Furthermore the documentation seems to be misleading 
with respect to the new semantics.

"Returns the result of streaming arg into a std::stringstream  and then 
out as a Target object. Note that spaces are significant in any 
conversion and are not skipped."

IIUC, this is no longer true for std::basic_string.

I cannot resist, I particularly like this one.

"Where non-stream-based conversions are required, lexical_cast  is the 
wrong tool for the job, and is not special-cased for such scenarios."

To me its a clear argument for not changing the std::basic_string semantics.

I got the impression that the majority on the list want's the change in 
string semantics and I am willing to accept this. But I would really 
like to see the documentation clearly state that strings are handled 
differently.
